Merci Pierre, Yes I agree and plan to move more to C/C++ and releasing the GIL when entering C/C++.
I also need to understand my original question re GIL and rescheduling. I fear that lock/unlock too often is also causing delays due to context switching. BTW do you have any hints/comments on SWIG/BOOST etc to glue PY and C/C++ ? Alan -- http://mail.python.org/mailman/listinfo/python-list
